Soil texture was controlled by the use of cultures of loam, 
sand, and gravel. Soil texture affects principally the moisture 
content and the air content of the soil, hence careful analyses to 
The following moisture 
determinations were made for sand, loam and gravel, which show 
the amount of hygroscopic water, the volume of pore space, and 
the amount of capillary water in each of these soils: 
‘determine both relations were made.
